Resistant Host Responses to Ten California Populations of Meloidogyne incognita.
Resistant and susceptible cultivars of tomato, lima beans, cotton, and alfalfa were tested with 10 populations of Meloidogyne incognita from different California locations. Nine of the populations differed in aggressiveness on the nine cultivars tested. Two populations were especially aggressive toward resistant tomato cultivars.
متن کاملTranscript analysis of some defense genes of tomato in response to host and non-host bacterial pathogens
The transcript levels of six defense genes including pathogenesis-related gene 1 (PR-1), pathogenesis-related gene 2 (PR-2), pathogenesis-related gene 5 (PR-5), lipoxygenase (LOX), phenylalanine ammonia-lyase (PAL) and catalase (CAT) were investigated in tomato plants inoculated with Xanthomonas axonopodis pv. phaseoli as a non-host pathogen and X. euvesicatoria as a host pathogen. Activation o...
متن کاملVariability of Meloidogyne exigua on Coffee in the Zona da Mata of Minas Gerais State, Brazil.
Minas Gerais is the major coffee-producing state of Brazil, with 28% of its production coming from the region of Zona da Mata. Four major species of root-knot nematode attacking coffee (Meloidogyne incognita, M. paranaensis, M. coffeicola, and M. exigua) have been reported from Brazil. To determine the variability in Meloidogyne spp. occurring in that region, 57 populations from 20 localities w...
متن کاملPlant Nutrient Partitioning in Coffee Infected with Meloidogyne konaensis.
Two experiments were conducted to assess nutrient partitioning in coffee (Coffea arabica cv. Typica land race Guatemala) infected with Meloidogyne konaensis. Nutrient levels were quantified from soil, roots, and leaves. In the first experiment, 500-cm3 aliquants of a Kealakekua Andisol were infested with four initial population densities of M. konaensis ranging from 0 to 1,500 freshly hatched s...
متن کاملHost Status of 32 Plant Species to Meloidogyne konaensis.
A host suitability study of 32 plant species to Meloidogyne konaensis included 54 vegetable cultivars, 12 field crop cultivars, one Gardenia sp., and two weed species. Host suitability was classified according to a M. konaensis reproductive factor: final population density (Pf) (eggs + J2) / initial population density (Pi) (eggs). The number of eggs per gram dry root, and a galling index was al...
